Company is a text completion framework for Emacs . The name stands for “complete anything”. It is nice.
(use-package company
:config
;; No delay in showing suggestions.
(setq company-idle-delay 0)
;; Show suggestions after entering one character.
(setq company-minimum-prefix-length 1)
;; Wrap around the when the end of suggestions is reached
(setq company-selection-wrap-around t)
(add-hook 'after-init-hook 'global-company-mode)
(global-company-mode t)
)
I also use company-box a better front-end for company
(use-package company-box
:after company
:hook (company-mode . company-box-mode))
